SPECIFICATION'forming part of Letters Patent No. 657,547, datedSeptember 11, 1900.

Application iled May 21, 1900.

T0 all whom it may concern:

Be it known that I, J AooB WILLIAM KAMM, a citizen of the United States,residing at At.- wood, in the county of Douglas and State of Illinois,have invented a new and useful Unloading Apparatus, of which' thefollowing is a specification.

This invention relates to unloading apparatus, and is particularlyadapted for the unloading of corn or other grain from a wagon to a cribor granary, although it will be understood from the followingdescription that the principles involved may be employed in apparatusfor other purposes.

The object of the invention is to provide a simple and cheapconstruction which will be eflicient in its operation and will beparticularly adapted for conveying corn from'a wagon to a crib and indumping the corn into `the crib through the usual' side door thereof;also, to provide means forraising and lowering the bucket andmanipulating the bucket in the dumping operation. 4

Further objects and advantages of the invention will be apparent fromthe following description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is anelevation showing the complete unloading apparatus andillustrat- Ing the position thereof with` respect to a wagon and a crib,from the former to the latter of which the corn is unloaded. Fig. 2 is aplan view of the carrier or traveler with which the bucket is engaged.Fig. 3 is a central longitudinal section of the traveler and showing thelatch mechanism thereof in elevationand engaged with thebucket-supporting pulley. Fig. 4 is a transverse section of the travelerwith the bucket-supporting pulley engaged therewith. Fig. 5 isatransverse section of the bucket and illustrating the means for latchingthe movable side in its closed position. V

Referring nowto the drawings, the unloading apparatus comprises,essentially, atrack 10, upon which the traveler operates, this trackbeing in the form of a cross-sectionally rectangular rail. This rail hasa series of hangers l1 in the form of bolts which are passed upwardlythrough the rail and have Seria1No.17,503. (No model.)

`secured to one of the rafters of the crib, it being understood thatthis apparatus is designed particularly for use in unloading corn into acrib.

In practice anumberof buckets are placed upon a wagon-hed from which thesides have been removed or upon a platform placed upon the holsters of awagon, and the corn is shucked directlyinto the buckets,from which it isto be discharged into the crib, the buckets being necessarily raisedfrom the wagon and discharged' into the top of the crib. During thehoisting and dumping operation the bucket is suspended from a traveler(shown in Figs. 2 and 3) which is slotted longitudinally to form twoparallel legs 2O and 21 a-t its upper side, and upon the upper ends ofthese legs are I'ixed plates 22 and 23, respectively, having slots 24and 25, in which are journaled supporting-wheels 26 and 27, adapted torestupon the upper surface of the rail 10 and support .the traveler. Theseparation of the legs20 and 21 is such as to permit free movement ofthe traveler along the rail and yet to prevent lateral displacement ofthe traveler, it being understood that, as shown in dotted Vlines inFig. 4, the rail 10 lies below the plates 22 and 23 and between the legs20 and 21. The slot of the traveler is continued through the bottomthereof, and between its sides and adjacent thebottom there is pivoted alatch 24', comprising an arc-shaped upper portion having alaterally-extending foot 25 at its lower end, this foot being adapted tolie in a horizontal position when operative. In the upper end of thearc-shaped portion of the latch there is formed a recess 27 and ashoulder 28 therebelow, and this recess and shoulder are designed forengagement by the si mi lar shoulder and recess 29 and 30 upon the endof a keeper 31, which is in the form of a rod pivotally mounted in thetraveler. The notched o r recessed end of the latch is adaptedtonormally lie forwardly, as shown in dotted lines in Fig. 3, and withthefoot ofthe latch retracted and in a slanting position; but whenengaged by the keeper it is held raised and with the foot in ahorizontal position, as

shown in full lines in Fig. 3.

be tilted, by reason of the pivotal connections of the rods 45 with thebucket, so as to dischargeitscontentsintothecrib. Afterdnmping thebucket is closed, and the latch-keeper is operated to cause the latch torelease the link and permit the bucket to descend to theV wagon. Thelink is then disengaged from the bucket, and the traveler is moved toassulne a position over the next bucket, the link being connected Withthis next bucket, and it is raised and discharged in the same manner asabove described.

In practice various modifications of the inven tion may be made, and anysuitable mar 5 terials and proportions may be used without ing the sideat the limits of its movement.
